The Kraft Insulin Survey: Who, What, Why?


In this video, we’re going to talk about
the Kraft insulin survey. We’ve mentioned it many times but we’ve never
really gone through a full who, what, why, when, and where. That’s what we’ll do in
this video. We’ll also talk about Joseph Kraft’s book, The Diabetes Epidemic and
You. Just briefly, who – who do we do these for? People who I suspect insulin
resistance for one reason or another but it’s not showing up very clearly in the
standard tests. Fasting blood glucose, triglyceride over HDL even OGTT. John
Roy Scheider was one of those folks as we mentioned before. He came in and said,
doc you I know you asked about insulin resistance and prediabetes. I check it
every year, my doc checks it every year. We know what we’re doing. We don’t have
it. We did the Kraft Insulin Survey and his blood sugar went up over 200,
actually close to 300. He realized at that point that he had not
only insulin resistance but full-blown diabetes and covered that in several of
his videos. Now, so those are the kind of situations where we’d want to look at
this. What is it? We’ll go into detail on the tests in just a few minutes. Why?
Again, we’ve covered that in other videos. Basically, if someone has insulin
resistance or full-blown diabetes, they clearly are not somebody. They should be
eating glycemic carbs at will. That’s something they need to be very much
familiar with and they need to start tracking their blood sugars using
continuous glucose monitoring like the freestyle Libre. So, where do you do it?
It’s – you can be – you can do it from your own home. We’ve also worked out something
with quests labs where we do something very similar. It’s a 3-hour insulin
survey. We’ve done a couple of videos on that. Again John covered one. These – I’ve
done a couple of videos where I actually looked. John’s covered the book.
Mine covers more of the history and the test results itself. So the history – it
was developed by a fellow named, doctor named Joseph Kraft. He was a pathologist.
The head of a lab, large lab in a large hospital in Chicago a couple of decades
ago. He wrote a book, The Diabetes Epidemic and You. It was based on quite
about 15,000 glucose tolerance tests that he did in his lab. These folks were
people that had been referred to the lab by their dogs for glucose tolerance
testing. Now, he did something a little bit different. The normal OGTT has 75
grams of glucose. You go in, your – your NPO or nothing by mouth for 8 hours. Then
you go in, you get a fasting glucose and then a 1-hour. Well, a fasting glucose
takes 75 grams of the sugary water and then tests the blood sugar again at at
least 1 hour and 2 hours. The Kraft prediabetes profile or insulin survey
is different in a couple of ways. You still do the nothing by mouth for 8
hours. You still do the fasting blood sugar but instead of a 75 gram drink, you
get 100 grams of glucose in that drink; and instead of 2 hours, you get
3 hours or even a 4-hour test. And instead of just looking at glucose, every
time you’re drawing blood you’re also looking at insulin. So we can follow the
insulin pattern and the amount of insulin that your body is putting out in
order to manage that blood sugar. It’s a – you can do – do this at home through one
of our – one of the labs that we work with. Meridian Valley lab or we now have
something that we’ve negotiated with quest labs to get it done in the
reference lab. Now, as John mentioned in his video and and some other folks have said, well my dog said this was rigged to fail.
A hundred grams of glucose well, or even 75 for the OGTT. Well again, one 20-ounce
bottle of – of soda is 78 grams of carbs and guess what, if you go to Mickey D’s
and get a a value meal, you get 190 carbs. 95 of those are sugars
so you got to watch out and think a little bit more deeply about what you’re
eating and what you’re drinking. Now, let’s go into the the results of the – the
book and the chapters itself. I wanted to cover some of that with you. So you begin
to understand why we keep referring back to this book. Out of those – of what,
14,000 tests that he did, he kept fairly good numbers and we’ll go
through some of the translation on what he saw. He – each chapter of about, what
chapters 31 through 35 or so, looks at a decade of life. So in other words, this is
the decade of life 51-60 year olds. In the number of – of these
Kraft Insulin surveys, he did where there were inpatients 51-60 was 2413. The
number out of that, that had a normal glucose tolerance was 1,300. So just over
half had a normal glucose tolerance. Impaired tolerance was 602 and diabetes,
full-blown diabetes was 508. The mean out of that group was 56 years and it goes
on to tell how many women, how many men tell us a little bit more about the
procedure itself and it says, the procedure was ordered by the physician
to exclude or diagnose prediabetes or diabetes. Now, here’s a little bit of
confusion and I will try to clear that up for you. The results were critiqued
with the American Diabetes Association guidelines for fasting blue blood
glucose and oral glucose. So what he’s saying here is this. They looked at the
fasting blood glucose. If it was less than a hundred ADA guidelines said you
didn’t need to be testing any further so you didn’t need an oral glucose
tolerance test. If that had – had been applied to this group of 51-60
year olds, 69% would not have been tested. So 69% of these people had
over or had a fasting blood glucose of a hundred or less. So again, most labs
would say, well you don’t need to do an OGTT. Well, again as he showed in
the beginning, almost half of them had an abnormal glucose tolerance test. So – or a
Kraft Insulin Survey. So that’s the point that you begin to see and actually even
docs and standard medicine these days understand, fasting blood glucose by
itself is not an adequate test. If you look at mine for example, in March of
2019, my fasting blood glucose was 84. It looked great but at 1 hour post oral
glucose tolerance or post 75 grams of sugar, my blood sugar went up to 184 so
I’d be in one of those groups. That’s just to repeat on those. Let’s look at oh
no – it’s not – it’s the 41 to 50 age group. So as you see, one of the things that
you’ll see as I go through these next few chapters, is this is very much an
age-related issue. I’ve said many times in many different videos. Most of us tend
to think, well the diabetes and prediabetes epidemic is really caused
by obesity, and I keep saying, if you look at aging, aging is probably a bigger
issue. The fastest growing group of of Americans as centenarians, hundred
year olds; and let’s look at aging over the next 3 or 4 slides. 41-50
year age group. Out of 1925, the normals were a hundred – 1231.
So again, that’s significantly over half for normal there. Maybe what,
60%. Actually over 60%. In the 51-68 group which would cover just a
few minutes ago, now that’s dropping. It’s 1302 normals over 2400.
Getting a little bit closer to half. Okay, now that we get up to the 61-70
year age group, 827 normal out of 1720 and pardon me,
these numbers have gotten moved around a little bit in is 1720.
Normal glucose was 827. Impaired glucose was for 64 and full-blown diabetes glucose intolerance was 429. So
as you can see, at this point between ages 60 and 70, less than half have a
normal insulin resistance or OGTT Kraft Insulin Survey or more than half have
insulin resistance or prediabetes. You know what, you remember the book that
we’ve mentioned many times, it’s Ginny Rule Blood Sugar 101 where she says, look
by the time we’re age 60, half of us have insulin resistance.
That’s from experience that they’ve seen with tens of thousands of diabetics; and
if you look at numbers from the CDC, just using hemoglobin A1c and fasting glucose,
those numbers would indicate it’s 1/3 of all adults, age 32 and above in the
country or 84 million of us. If you look at the UCLA study in California,
it’s over half have prediabetes starting at age 30. So you start looking at these
numbers and you start realizing, dang, if you did an insulin – Kraft insulin survey
on these people, how many more would you find with insulin resistance and as you
start looking at age groups what’s going on there? In the 71-80-year old age
group, this is – you look at this and okay out of a total n of 932, the – the normals
were what just over a third. So 2/3 of the people had insulin
resistance and or complete diabetes. So again, I hope that helps give you some
perspective. Now it’s not entirely comparable and before you start saying,
we’ll wait a minute Brewer, those – let’s just stop and and think just a minute.
How were these numbers obtained? These were docs referring a patient where
they had some sort of suspicion. So the numbers are not totally comparable to
either the CDC or the UCLA numbers. And the CDC and UCLA numbers are not totally
comparable but again what they do show is significant increase in insulin
resistance and diabetes as we age and they also show the – the old normals or
the old tests like fasting blood glucose just are not adequate. The 81-90 year
old group out of a total of 210, only 65, less than a third at this point have
normal glucose tolerance. So one other thing that he showed in his, as he went
back and analyzed these numbers and these, what, 14,000 tests that he did
was some significant patterns; and these patterns you see, because it’s an insulin
survey. In other words, he kept getting the insulin tests at the same time he
was getting the glucose tests. This is a normal at zero or fasting blood sugar,
blood sugar’s around 80. After a half hour went up, peaked at about at 120.
Came down to just around a hundred for 1-hour and the 2-hour
and then dropped down below to 80 or so. At the same time, blood – blood
insulin went from 2 or 3 up to 50 at peak and then again began to
come back down. That was normal pattern. Pattern 2, the
blood sugars started going up to 140 and this was at an hour. It was delayed, as
you can see, the next 3 patterns do show a delay. A half-hour delay, a
1-hour delay, and a 2-hour delay. Now what does that mean, well there are different
levels. Again, if you read Ginny Rules’ book, there are different levels of a
different time periods of insulin response. Our body does store insulin, so
when we get challenged with an increasing blood sugar, there’s an
immediate release of that stored insulin and then after that, the pancreas begins
to make more insulin. So what you’re seeing here, appears to be decreased,
further and further decreases in that stored insulin response; and what’s
happening then is it’s taking longer and longer in patterns 2, 3a, 3b and – and well
3a and 3b to get that insulin built up so it takes in the blood sugar down and
manages the blood sugar. Now he’s – he showed pattern 4 as well where the
numbers went way up, went to like what, 250 for blood sugar and also went way
high for insulin as well and that he labeled as hyperinsulinemia. So that is
actually true resistance, where your blood sugars are going up, your insulin
values are going way up as well but your blood sugars are just not coming down.
Now that’s considered to be a late stage of pre-diabetes or insulin resistance, in
fact, that is often coming right before a time when the beta cells in the pancreas
have just worn out, they’re not making insulin anymore, are significant amounts.
With that pattern, insulinopenic is what they call it, penia meaning very
little. It’s making very little insulin at that point. The blood sugar is going
up to 300, meanwhile, the insulin is still not making it up to 50. So I’ve traveled
very quickly through this survey. Some of it may sound a little bit confusing. If
it is, please make some comments below and I’ll see if I can clear those up. If
